I believe this is from the 1920's. Nice, cedar lined chest great for storing items with no worries about bugs. These are a lot more rare than the Lane models of similar time era.
A little bit about the company. The "Roos Manufacturing Co." of Chicago was established in 1871 by Edward Roos (born in Germany in December 1848), died in 1906. He had several children including Otto (born 1877) and Edward (born 1880). Otto took over the Roos Manufacturing Company when his father died in 1906. They did manufacture cedar chests, but it is unclear when they started. The business began making curtain rods and later wooden boxes. They used a rooster in several variations in some of their logos.
The chest is fantastic inside, but may need some restoration or work on the outside. As with most chests of this age, they used a thin plywood or veneer type material for the outside and it is prone to cracking, etc. Overall, not a bad chest.
